Hans,

In mfun-004.tex, I find:

\startuseMPgraphic{axis}
   tickstep := 1cm ; ticklength := 2mm ;
   drawticks unitsquare xscaled 4cm yscaled 3cm shifted (-1cm,-1cm) ;
   tickstep := tickstep/2 ; ticklength := ticklength/2 ;
   drawticks unitsquare xscaled 4cm yscaled 3cm shifted (-1cm,-1cm) ;
\stopuseMPgraphic

\startlinecorrection[blank]
\startMPcode
   \includeMPgraphic{axis}
   drawpoint "1cm,1.5cm" ;
\stopMPcode
\stoplinecorrection


If the axis graphic is going to be "reused" over and over again, why  
didn't you use \startreusableMPgraphic?
